While your friends have made and remade (or flat-out nixed) their New Year's resolutions, you're on your way to the body you want, thanks to Part I of our 12-week program last month.

Now, take it up a notch: Zero in on foods that give you energy, exercises that give you strength, and mental techniques that give you power. We called in Jillian Michaels the trainer who gets serious results on The Biggest Loser, to help you do it. (Find out more about her at jillianmichaels.com.)

With this program, you could lose 5 to 8 pounds a month — that's 15 to 24 pounds by March. This isn't a lose-it-fast-then-gain-it-back scheme; this is the plan that works for life.

About your trainer: Jillian Michaels
Jillian Michaels not only gets in her clients' faces, but also stays in their minds, so every time they think about making a bad choice, they know how to talk themselves out of it. Michaels knows how you feel (and what your excuses are!). She was once an overweight kid and teenager (age 13 and 155 pounds), and dropped the weight by eliminating junk food, white bread, and taking up martial arts. She didn't lose the final 10 pounds until she started doing calorie math and making sure she consumed less than she burned — the cornerstone of the food plan she offers here.
